400 Wheel Spindles

[AshimotoK0]

I am currently fitting rebuilt wheels to my '75 400/4 that I restored in 1986 !
I couldn't find NOS DID rims in '86 so I used Suzuki Takasago rims (bought from Queens Park Motors
Oddjobb    ) and non-standard un-butted spokes. Anyway, with eBay and internet, (not around in the mid '80s ! ) I have just rebuilt replacement wheels with the proper period DID non-side-scripted rims and the correct Honda spokes.

I noticed that my Aug 1975 bike had a hex headed rear wheel spindle fitted and it's not correct as it should be the -286- part ..like the CB250K , although I believe  it was BZP finish on the CB400F,  not chromed. Also I noticed that among my collection of front wheel spindles, some have hollowed ends and some are solid. I think the '75 should have the solid end,  BZP finished version. Any ideas? I think my original rear spindle must have been from a late F2 model or perhaps a CJ250T.

Hi Ash,
My '75 400 (first reg Nov 75) UK bike has a round head rear spindle (with tommy bar hole) and is (and was) BZP.  Front spindle is solid end BZP.  The 350 front is the same but the rear is round with hole and chromed.

My 1978 400 has the hex head rear spindle.

That's probably what you expect for a later build.

As far as I can remember early 400s had round end with tommy bar hole, my 75 has, later with hex head which my 78 has, according to my parts book the rear spindle changed at frame number 1065686 but no indication as to which spindle.
I have three front spindles, and all have the hole, the parts book doesn’t show that there was a change in front spindle.
All BZP.

The hex head one is a bit of a mystery as it doesn't seem to show in any 400F or CJ250 parts book I have. I discussed this a while back with Chris Rushton,  who knows a thing or two about CB400F's. He found a NOS one but it was too long for the 400F  and I guess a CB250N part. I have found a -312- (SL350) part that I think is the correct style and length but not showing as ever fitted to the 400F. The round rear axle with tommy-bar hole one was, I guess the 286-010 part when chromed and 286-020 when BZP.

I saved the pics of the 'Push-mile only' CB400F2 that Silverstone auctioned a while back and it clearly shows the hex rear spindle and the non-hollow front spindle. I guess the hollowed front  ones I have came from a CJ250T.

That's the first time I've clocked the black side stand spring.  I have bought DS ones in Honda bags with labels that were BZP.

As Julie said at the time it was auctioned ..... she wasn't at all convinced that that bike was an unmolested 'push-only' mile example.

Whoever painted that spring also had a bit of an attempt at re-painting the black line around the gen cover badge - and failed!

I have had hollow and solid front spindles in Honda packets with the same part number Ash. I think it was just two different suppliers mate.
All 400/4's i have had through the work shop had flange nut rear spindles and all 350/4's have round head rear spindle. Not sure if they started off with the round head from the 350/4's and then went on to the nut type.

Are they Showa or FVQ rear shocks Ash, I've tried to zoom in on the photo but the sticker is too far gone. Maybe Piki can make some if he has a phot to use? I'd like to get a set made for my genuine 400/4, there are no stickers on my rear shocks.

Piki definitely does the SHOWA stickers.

Mine is a pretty early model Graham and deffo had the round BZP type originally. Also early UK model CB400F's had a different mudguard as they still had the front number plate fitted and were actually a -369- CB250G5 part with a different shape cable guide also. I didn't know about the different shape cable guide until ChrisR told me about it.

The mudguards were just parts to Honda. Though in the UK we scraped front plates in 1973 they would of fitted them as it was on the assembly line. I have seen UK CB750K2 with front plates right up to 1975

Spot on Trig, time to unearth a tear jerking memory!! Purchased in late '74, front plates removed and screwed to garage wall late '75. Bike was sold in '77 complete with number plate as the collection fad had not really taken off then. Ho hum. (Plate is now worn by a 500 Mercedes!)
